STDOUT vs STDERR
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
.. tip::
|
||
|
|
所有的错误信息都应该被导向STDERR。
|
||
|
|
|
||
|
|
这使得从实际问题中分离出正常状态变得更容易。
|
||
|
|
|
||
|
|
推荐使用类似如下函数，将错误信息和其他状态信息一起打印出来。
|
||
|
|
|
||
|
|
.. code-block:: shell
|
||
|
|
|
||
|
|
err() {
|
||
|
|
echo "[$(date +'%Y-%m-%dT%H:%M:%S%z')]: $@" >&2
|
||
|
|
}
|
||
|
|
|
||
|
|
if ! do_something; then
|
||
|
|
err "Unable to do_something"
|
||
|
|
exit "${E_DID_NOTHING}"
|
||
|
|
fi
